Frequently Asked Questions
  • What is Control III Disinfectant Germicide?
    Control III Disinfectant germicide is a hospital grade disinfectant. It contains a special combination of two quaternary compounds, which makes it a highly effective, broad-spectrum disinfectant. By providing a hospital grade disinfectant for home care, you are assured of the same infection control at home that is available in hospitals. Mixed at a rate of 1 ounce to a gallon of water, a use solution of Control III Disinfectant can be created which can be used on a variety of hard surfaces and equipment.

  • Is Control III Disinfectant germicide widely used for home care respiratory therapy and for sleep equipment?
    On a national basis, Control III Disinfectant has been used for over 25 years for the disinfection of home care respiratory therapy equipment.

  • Does Control III Disinfectant Germicide harm the environment?
    Control III in use solution is environmentally friendly. When released into sewage or septic systems, Control III breaks down rapidly, without harm to human, animal, or plant life. The used solution can be disposed of down the drain and requires no special disposal procedures.

  • Is Control III Disinfectant germicide irritating to the skin and eyes?
    Concentrated Control III Disinfectant, as it comes straight out of the bottle, is a primary skin and eye irritant. One should avoid contact with the concentrate on skin and in eyes. The diluted solution is not a skin irritant. If you do get it in your eye, you should rinse it thoroughly with plain water for 15 minutes. Call a doctor if redness or irritation persists.

  • Does repeated use of Control III Disinfectant germicide harm equipment, or degrade the material?
    No. Control III does not contain drying chemicals that harm rubber, plastic, or metal. Furthermore, the use solution does not contain caustic or corrosive substances which harm equipment or cause irritation to the face if masks are disinfected with it.

  • Is Control III use solution safe to use around children and/or pets?
    Yes. If the use solution is gotten on the skin, it should be rinsed with plain water.

  • What types of pathogens are killed by Control III Disinfectant germicide?
    With a ten minute contact time, Control III is effective against a broad spectrum of bacteria (gram-negative and gram-positive), viruses, and fungi. These include, but are not limited to, HIV-1, Herpes simplex, Adenovirus Type 2, Staphylococcus aureus, Pseudomonas, and E. coli, H1N1 (swine flu) virus, and MRSA.

  • Does Control III Disinfectant germicide kill spores?
    Control III Disinfectant does not kill spores; thorough pre-cleaning of surfaces prior to disinfection can contribute greatly to the reduction of spores on surfaces.

  • Does Control III Disinfectant germicide kill Tuberculosis?
    Control III Disinfectant germicide does not kill TB. However, tuberculosis is not usually a threat in a home care setting.

  • How can Control III Disinfectant kill bacteria if it is relatively non-toxic?
    Toxicity does not determine bactericidal effectiveness. Control III Disinfectant germicide�s mode of action attacks bacteria, viruses and fungi by a chemical process while maintaining a low overall toxicity level.

  • I currently use vinegar and water to disinfect my equipment, as I hear it works just as well and is cheaper than Control III. Why should I start using Control III?
    Some patients have heard that vinegar is an alternative means of disinfecting equipment that is more �natural� and effective and cheaper than Control III. In fact, none is true. Vinegar is more of a �household name� than Control III. It is not more �natural� Control III also kills significantly more organisms than vinegar. Lastly, because of its concentrate form and its re-usability, it is actually 8 times cheaper than vinegar to use! Don�t forget that Control III also has a much more pleasing odor.

  • Should equipment be pre-cleaned before disinfecting?
    Proper pre-cleaning of equipment is the most important step in disinfecting your equipment, regardless of the brand of disinfectant you use. It removes the gross soil and bacterial spores which may have contaminated the equipment. After pre-cleaning, all equipment should be thoroughly rinsed with fresh water before being disinfected.

  • What should be used to pre-clean the equipment?
    The equipment should be pre-cleaned with any general purpose detergent, such as a dishwashing soap like Joy, or Palmolive. Do not use bar soap however, as some of these soaps contain ingredients which are incompatible with Control III Disinfectant. A thorough rinse with clean water is essential. Regular tap water is fine � distilled water is not required.

  • Do excessive heat or cold affect Control III Disinfectant?
    Excessive heat or cold will not harm Control III Disinfectant. If the concentrate has been subjected to extreme temperatures such as freezing, allow it to return to room temperature and shake vigorously.

  • What type of container should be used for soaking?
    Food grade plastic containers, such as Tupperware or those made by Rubbermaid, are recommended for soaking. This is the type bucket we provide in our home care kit. We recommend keeping the use solution in an airtight container when not in use to reduce contamination and evaporation of the solution. Do not use a PVC container, as it may become tacky to the touch.

  • How long does Control III Disinfectant last?
    Control III Disinfectant, as a concentrate in its original container, has a shelf life of five years. Once a solution of Control III is made up (in a dilution of one ounce per gallon of water), it can be reused for up to 14 days before being discarded. Should the solution become visibly dirty prior to 14 days of use, or has been used extensively in the disinfecting of many pieces of equipment, it should be discarded, and a new solution prepared.

  • What is the recommended soak time for Control III Disinfectant?
    Ten minutes is the soak time required by the EPA. Soak periods of more than ten minutes will not provide better disinfection. If disinfection of hard surfaces is desired, Control III solution should be applied in such a manner that the surface remains visibly wet for 10 minutes to achieve optimal results.

  • Is a rinse required after disinfecting with Control III Disinfectant?
    Instructions for use call for rinsing of equipment after disinfecting. If you are not planning to use the equipment right away, we recommend that equipment be allowed to air dry after rinsing with Control III. Store the equipment in a closed container or in Ziplok� type bags. Please note that some PVC tubing or rubber parts may become tacky if they are not rinsed immediately after soaking.

    CXC Notes: Hello, We're not sure why you would give a disinfectant product a 1 star review because it is strong and does what it says on the bottle which is specifically to disinfect and clean medical equipment, heat sensitive instruments, and tubing. The back of the bottle also provides information on using Control III with softer items like fabrics and laundry. Control III has been used in hospitals, home care situations and by CPAP users for years; but it is concentrated so it needs to be diluted before use as indicated on the instructions. We do provide the complete bottle label and instructions on our website, in the references section on the product pages, for your review as well. Sleep well!

  • An extra sterilizing precaution


    This product actually popped up on my Facebook page with another company so I decided to check it out. Then I did some price comparisons and had by far the best price. It seemed too good to be true, but I got the product promptly and I am using it.

  • Excellent product


    I have been using this product for 6 years to sanitize some of my CPAP equipment. I didn't do any scientific tests to see if it really works but I have not had any issues like mold or affecting parts like the mask cushion. I'll keep using it since I don't like the smell of vinegar!

  • Couldn't be better


    I bought a small bottle of Control III for less than $5, they didn't charge me any shipping, which may have been a special rather than regular operating procedure, but who cares, the package went from New Hampshire to California in 3 days. I really don't see how it could have been better.

  • It does the job!


    I’ve been on a real journey regarding the use of CPAP! Spent the first few weeks working to get used to wearing a mask at night, and fairly quickly became accustomed to it. Shortly thereafter, I began to experience feeling ill, and went thru several rounds of antibiotics, and I experimented with various humidity settings. Bought a SoClean unit and a bottle of the Control III concentrate, and began a daily regiment using both products. Every morning after waking, I empty the water reseviour from the night before, I add about a capful of Control III and fill the reseviour with hot tap water. I add my silicon face mask and 90 degree plastic joint to the solution, give it a vigorous shake, and let it sit for about a half hour. Then, I take each piece, one at a time from the solution, and rinse them thoroughly with very warm tap water, let them dry for about a hour, and drop everything into the SoClean unit. This method, while a bit tedious, has allowed me to stay “illness free” for almost four months now, and I feel very good. The Control III and SoClean products are top-notch, and are very effective!

  • Relieved


    Have had my CPAP for over 6 years. I've been cleaning it periodically with soapy water. Never felt that I was doing the best job. I now feel that my equipment is disinfected and my health is protected. Does leave a medicinal smell, but used PurSleep Vapor Clear from this site and it did the trick.

  • Works well; Documentation could be better


    I use a TAP PAP, and my nose was getting red and a bit crusty where the nasal pillows rested on my nostrils. I figured it was probably some bacterial thing and I needed better cleaning, so I ordered some of this disinfectant. It worked beautifully.
    The solution is concentrated: it only takes about 1-1/2 teaspoons and a quart of water to make a dunking solution that will last for two weeks (after which you dump it and make a new batch). I dunk my TAP PAP in it each morning for 10 minutes, rinse it in warm water and set it on a clean towel to dry, and no more skin irritation.
    The stuff seems to be intended for medical laboratory use, based on the directions. They talked about testing the solution's strength with test strips (not included, nor indeed even described in any detail), and ensuring a minimum strength of 1000ppm (parts per million); the latter begging the question: 1000 WHAT ppm? Then they say to run hot water for 3 minutes before rinsing the stuff off (flushing any bacteria out of the plumbing, I assume). Hey, we're in the middle of a drought, here! Anyway, I'm not too worried about super-sterility; I'm just putting the appliance in my mouth and against my nose, not performing surgery with it. Plus which, the TAP PAP will deform if you hold it under hot tap water for more than a few seconds. For me, a quick rinse with warm water is just fine.
    So 5 stars for performance, minus one star for mediocre directions.

  • Great Product


    This product is wonderful! I was hesitate to use it on my pillows after reading the bottle, but if you follow the diluting instructions, it works just fine. My pillows and cushion did not dry out, came out clean and disinfected and the product left absolutely no odor. I soaked my hoses in the solution for ten minutes, as directed, and they came out nice and refreshed. It was like having new equipment!!
